Model-Based Derivative-Free Methods for Convex-Constrained Optimization

Matthew Hough, Lindon Roberts

We present a model-based derivative-free method for optimization subject to general convex constraints, which we assume are unrelaxable and accessed only through a projection opera…

Scalable Subspace Methods for Derivative-Free Nonlinear Least-Squares Optimization

Coralia Cartis, Lindon Roberts

We introduce a general framework for large-scale model-based derivative-free optimization based on iterative minimization within random subspaces. We present a probabilistic worst-…
